Industry giants like RedHat and NetApp have adopted ServiceNow for their operational needs, and it is evolving as the number one platform choice for IT Service management. ServiceNow provides their clients with an add-on when it comes to baseline instances, where scripting can be used to customize and improve the performance of instances. It also provides inbuilt JavaScript API for scripting and improving your JavaScript instance. This book will initially cover the basics of ServiceNow scripting and the appropriate time to script in a ServiceNow environment. Then, we dig deeper into client-side and server-side scripting using JavaScipt API. We will also cover advance concepts like on-demand functions, script actions, and best practices. Mastering ServiceNow Scripting acts as an end-to-end guide for writing, testing, and debugging scripts of ServiceNow. We cover update sets for moving customizations between ServiceNow instances, jelly scripts for making custom pages, and best practices for all types of script in ServiceNow. By the end of this book, you will have hands-on experience in scripting ServiceNow using inbuilt JavaScript API.

In this chapter, we looked at the advanced side of client scripting. We saw how we can use UI actions to run client-side code and run client- and then server-side code. We also took a look at the all-important AJAX call for an efficient way to call server-side code from the client. Lastly, we had a look at some examples of how to use these advanced client-side techniques.

We will move on to the server side in the next chapter and see how to get started writing server-side script. This includes business rules, UI actions, and access controls. We'll also look at when these scripts should be written, how to test them, and some practical examples to help you get started.
